Application filed July 1812i Serial 11,196.

To all whom 2'25 may concern:

Be it known that L- lfiininr: Dnnn' 1mins a citizen of the United States,

to. igniters oi the n'mlce-mnhbreak electric spark type, and consists oi means whereby the condition of the firing points Within the engine c 'lindor can be determined without removing the igniter; the source of current used for the ignition may be tested by observing it spark produced between external contact points; and the timing of the internal or igniting spark determined Without ren'ioving the igniter from the cn ine cylinder.

Figure 1 is an end view 01' the igniter', embodying my invention. Fig. 52, a view looking down on some.

Like figures of reference denote the some parts Wherever they are shown.

For the sake "of illustration a well known form of ignitcr is shown, having the usual fixed and movable electrodes, the fixed electrode being insulated from the othcr pa As this construction is Well known, and as my improvement may be used with any form of igniter, 1 will not describe some in detail, but describe only the auxiliary ports constituting my invention.

To the outer end of the movable Contact stem 1 is attached a' member 2 carrying it contact 3. To the fixed Contact stem. l is attached the member 5 carrying the ad justablc contact screw 6. A spring 7 provided for locking this screw after adjnstment. Piece 5 is kept from turning by. the om 8 surrounded h insulation 9. or

in. any suitable manner.

One side of the source of current used with the igniter being connected to the flange carrying the movable electrode, and the other side to the nut 10 of the insulated electrode, when the" igniter is operated in the nsnal mnnnens spark is produced botvvsen the firing contact 11 and 12 of the fixed and movable olsctrcdes, provided the screw 6 is so adjusted that it does not touch the contact 3. In fact the operation is as usua Letters listcnti ll? in csso oi trouble, it is J; tho firing contacts 11 and s fonl out of. adjustment, is only adjust screw until it touches and a/spar; results. it"is evident to circuit and source of energy are {in l i, the trouble is in tho firing contacts adjustment Thus the condition of. ing contacts readily detcrmined out removing the ignites: from. the sng inc and Without trouble or d To test the source of cnrrsnt, it only necessary to proceed just dcscribcd,

spark between the auxiliary ca .ii zind so 3 indicating" at once co: battery or other source of 2;

This is oi? particular-r odvon when on alternating current engine tun d nnigneto is employed as with such a device the COKE? 5 inon expedient 01"- disconoccting; one oi the battery Wires and topping it on the binding post and obsorving the spark, cannot employed as tho engine must be in motion to turn the :nsgnoto before any current is available, and the break or topping must take place exactly when the magneto is producing the PGEllC of the cnrrcnt wove, otherwise no saork or s lt'sinla one will suit, which is deceiving to the true con dition of the magneto.

In properly timing; the ignitsr, 3 and 6 are brought iogi'l or, and the screw 6 slowly backed oi? until no'ifnrther spark results. lit is now evident the s'psrk is being produced at the contacts and 12, and the timing can be observed and the igniter adjusted to s nicety by method.

While l have shown but one form of auxiliary conloct: many other arrangements are obvious to those skilled in i" c mt deem all such arrangements to be Within scope of my invention, -which broadly the comhins'liqsi with s snd-broslzi i of on external Contact.
